Abstract: A drawer assembly (2) comprises a drawer (4) which is mounted for sliding movement on a pair of floating rails (18) which are themselves slidable with respect to the sides (8) of the housing (6) of the assembly (2). Each floating rail (18) slides in an elongate recess (16) in a respective side wall (12) of the drawer (4). The sliding movement is limited by the engagement of a drawer element (42) with the ends of a slot (40) in the rail (18). The element (42) can be pushed through a hole (44) in the side wall (12) of the drawer (4), through the slot (40), and then twisted to lock the rail (18) against lateral movement with respect to the drawer (4). 
     Each rail (18) is mounted for sliding movement with respect to the housing (6) on a pair of bearing elements (22) disposed inside the rail (18) and hence inside the recess (16) in the drawer side wall (12). The rail (18) is snap-fittable over flanges (38) on the bearing elements (22). Each of the bearing elements (22) is an integrally-formed unit.

Abstract: In a drum brake assembly a pair of brake shoes (12, 14) are carried by a backing plate (10) and are engageable with the brake drum (18) to effect a service brake application. A parking lever (26) co-operates with the pair of brake shoes (12, 14) to engage the shoes with the brake drum (18) and effect a parking brake application. A connector (34, 84, 94, 96) is slidably carried by the backing plate (10) and pivotally anchors at least one of the brake shoes (12,14) to the backing plate. The connector (34, 84) or another structure (128) transmits braking torque from one brake shoe (12) to the other (14) only during a parking brake application. The connector is releasably secured to the backing plate in a fixed position by a latch (36, 88, 114) which is connected to the parking lever. Movement of the parking lever to a position effecting a parking brake application causes the latch to release the connector for sliding movement relative to the backing plate. When a service brake application is effected, the connector remains fixed to the backing plate and the brake functions as a non-servo drum brake. When the parking brake is operated, the connector is released by the latch and is movable in the direction of brake drum rotation. Consequently, the brake functions as a servo drum brake during parking brake applications.

Abstract: The invention provides an AC electric energy metering system including an input module [Fig. 1 (12)] and a sample and hold circuit (14) which cooperate to produce sample values representative of the instantaneous magnitude of three-phase line voltages (V A , V B , V c ) and line currents (I A , I B , I c ) delivered to a load by a power distribution system. The sample values representative of the line voltages are input directly to a multiplexer (31). The sample values representative of the line currents are input to the multiplexer both directly and through ranging amplifiers [Figs. 1, 4 (30)]. When the sample values of the line currents are below a predetermined magnitude, the sample values amplified by the ranging amplifiers are used, thus increasing the accuracy of the metering system. The sample values are input to an analog-to-digital converter (33) where the sample values are digitized. A control circuit (36) calculates a plurality of indicia of the AC electric energy quantity delivered to the load from the digitized data. An output module (45) is responsive to the control circuit for displaying, recording or transmitting the calculated indicia. A timing circuit (39) times out a predetermined sample timer interval. At the end of the interval the control circuit produces new sample values and resets the timing circuit. The timing circuit is constructed so as to recognize a plurality of failure modes of the control circuit and reset the control circuit in response thereto thus improving the reliability of the metering system.
